Accessory mode is when your engine is running but your car is not in drive. The engine is running to power things like your lights your radio and your air conditioner. It’s not designed to run your car for an extended period of time.
Why is running your engine in accessory mode for too long a problem? There are a few reasons.
First your car is not designed to cool itself down while in accessory mode. The cooling system is designed to work while the car is moving so it can draw in air to cool the engine. When your car is stopped the engine can overheat.
Second your battery is not being charged while in accessory mode. So if you run your engine for too long your battery will eventually die.
Third your car is not designed to run all of its accessories for an extended period of time. The alternator is only designed to power the car’s accessories for a short period of time. If you run your accessories for too long you can overwork the alternator and it will eventually fail.
So how long can you run your car in accessory mode? It depends on the car but most carmakers say 10-15 minutes is the maximum. If you’re unsure it’s best to err on the side of caution and keep it under 15 minutes.
